Title: Method for deciding shrinkage cavity of cast iron
Inventor: SUZUKI HISAO
IPC: B22D2/00
Filed: 1986-10-16
Abstract: PURPOSE:To permit simple, sharp and quick decision of whether a shrinkage cavity exists or not by deciding the presence or absence of the shrinkage cavity from the presence or absence of the part where the temp. rise stagnates prior to the attainment of the max. ultimate temp. in the temp. change curve of a molten metal. CONSTITUTION:The molten metal is poured into a metal into which a thermocouple is inserted; thereafter, the molten metal is cooled and the part where the temp. rise stagnates before the attainment of the max. ultimate temp. is plotted in the temp. change curve of the molten metal. Said part where the temp. rise stagnates is not plotted in the case of a casting having the shrinkage cavity. The presence or absence of the shrinkage cavity is thereby easily decided from the presence or absence of the part where the temp. rise stagnates before the attainment of the max. ultimate temp. in the temp. change curve of the molten metal.

Title: Magnetic tape device
Inventor: MINODA HIDENORI
IPC: G11B15/087
Filed: 1992-09-16
Abstract: PURPOSE:To almost surely perform recording and reproduction over plural recording areas without interrupting the recording/the reproduction over the long period of time when the recording area are shifted. CONSTITUTION:When the recordable time of a sector A elapses after the recording is started, the direction of a head and a tape traveling direction are reversed at the point P of a magnetic tape 18 and the recording is shifted to the sector B. In such a manner, the recording is not performed for a trailer tape 19 which is a non-magnetic part and the time for generating recording omission can be substantially shortened. At the time of the reproduction, when the reproduction is started from the sector A, the time same as the above-mentioned recordable time elapses and a reverse marker 20 recorded at a reverse position at the time of the recording is read by the head, the direction of the head and the tape traveling direction are reversed at the point P and the reproduction is shifted to the sector B. Thus, the reproduction is not performed for the trailer tape 19 and the time for generating the sound interruption can be substantially shortened.

Title: Oil feeder
Inventor: MURATA MITSURU
IPC: F04B39/02
Filed: 1983-12-28
Abstract: PURPOSE:To prevent the seizure and breakage of a compressor shaft, by tapering the front end portion of a helical spring and immersing the front end portion in stored lubricating oil to supply the oil by the spring. CONSTITUTION:When a shaft 4 is rotated, lubricating oil 12 is pushed up along the spiral inside of a closely fitted helical spring 22 to horizontal holes 16, 17, 18 and supplied to clearances 19, 20, 21. If the inside diameter A of the spring were larger than that of a vertical hole 14, the oil 12 would collide against the lower end 25 of the shaft 4 and the oil supplying force would be greatly decreased. In fact, the inside diameter A and that of the vertical hole 14 are almost equal to each other so that the lubricating oil 12 is smoothly pushed up. About 1.3 to 2 times as much oil supply power as a conventional lubricating pump 13 is obtained by the closely fitted helical spring 22. As a result, the shaft 4 does not seize on an upper bearing 9, a roller 6 and a lower bearing 10 during the operation of an enclosed compressor 1.

Abstract: PURPOSE:To easily measure the surface roughness of a surface to be measured even when the surface to be measured is sectioned in an arcuate shape by setting a work so that it swings freely around the center of curvature of the surface to be measured as an axis. CONSTITUTION:The shaft 4a of a work holding base 4 where the work 7 is fitted is inserted into a sleeve 3 and the base 4 is moved up or down through a pinion 5 to make an adjustment so that the axis O of rotation of a clevis 2 is aligned with the center of curvature of the surface 7a of the work 7 to be measured. In this state, while the work 7 is swung around the axis O as the center relatively to a measurement part 15 by a pump P, a cylinder 9, etc., the difference between the quantity of measured surface irradiation light by a projection device 16 and the quantity of reflected light by a photodetecting element 27 which varies according to the surface roughness is computed by an arithmetic device 20. Consequently, the roughness of the surface to be measured which is sectioned in the arcuate shape is easily measured without contacting.

CONSTITUTION:The width R11 of fins in the group 13 of fins, which are fitted to the group 11 of heat transfer tubes at the inflow side of airflow B, is widened broader than the width of fins in the group 14 of fins for group 12 of the heat transfer tubes at the outflow side of the air flow B while the pitch D11 of the heat transfer tubes in the group 11 of the same is lengthened longer than the pitch D12 of the heat transfer tubes in the group 12. According to this method, the efficiency of the fins in the group 13 of the same becomes lower as compared with the efficiency of the fins in the group 14 whereby the frosting on the heat transfer tubes in the inflow side of the airflow B is mitigated. On the other hand, the width of ventilating passages themselves for the tubes in the inflow side of the airflow B becomes wider. Accordingly, the amount of frost adhered to the fins in the group 13 and the heat transfer tubes in the group 11 at the inflow side of the airflow B per unit area can be made equal to the amount of frost adhered to the fins and tubes in the groups at outflow side of the airflow B is whereby the ventilating passages may be secured for along period of time. As a result, the period of defrosting may be lengthened.
